Implication

Theoretical modeling demonstrates accurate mixed-mode stress-intensity factor calculations in isotropic solids, highlighting improved computational efficiency using far-field data.

Key Points

To establish an accurate, computationally efficient method for analyzing two-dimensional mixed-mode crack problems in isotropic solids using conservation laws of elasticity.
Formulated mixed-mode stress-intensity factor evaluations through conservation integrals combined with known auxiliary elastostatic solutions.
Extracted necessary mechanical parameters directly from far-field regions rather than near-tip singular zones.
Validated the numerical framework against benchmark literature solutions and applied it to cracks originating from circular holes.
Demonstrated superior numerical simplicity and computational efficiency relative to existing fracture analysis methods.
Successfully calculated mixed-mode stress-intensity solutions relying exclusively on far-field data.
Accurately solved complex, practical engineering configurations involving cracks emanating from circular cavities.
